And no, Jon's regal furs he wore during season seven were not woolly Ikea rugs. Clapton specified that the Night's Watch capes were all made with Ikea rugs, which means Jon's costume for the just first five seasons included a wool floor mat.

Still confused as to how exactly that rug becomes a cloak? Ikea decided to help out "Game of Thrones" fans and post their own instructions. Even though these guidelines don't come from Clapton, it does seem legit.

After seeing how the rug essentially just needs a hole in the center before it transforms into a shoulder-covering cloak, it's funny to look back at Jon Snow and Sam's scenes and realize they're wearing small carpets.

We never would have guessed that those were rugs.

Clapton said the costume team added leather straps and distressed the rugs in order make them more believable in the world of Westeros.
